Tutorial quote: rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well.

Tutorial quote: Not everyone has reliable, always-on Internet access. For some, reliability has to come through software, not hardware. Fortunately, protocols designed to work around slow and unreliable networks still work. Christophe Prevotaux demonstrates how to set up FreeBSD, Postfix, and SSH to send and receive email via UUCP.

Tutorial quote: If you are using LDAP or NIS to manage users you might discover users having problems because they don't have a home directory on each machine they can connect to. Thankfully there is a simple solution for creating home directories upon demand for users.

The Pluggable Authentication Modules library, or PAM, is a collection of shared libraries which control how users login to systems. There are a number of modules installed which can be used to restrict user access to systems in different ways. There are also several utility modules which can be used to customise login behaviour.

Tutorial quote: Live CDs can be useful for testing an operating system or performing special operations -- assuming there's a live CD distro that does what you need. Unfortunately, if you are running a special application, especially one you wrote yourself, no live CD will be tailored exactly to your needs. But creating you own live CD is easier than you might think, with Slax and its easy customization utility MySlax Creator.

Tutorial quote: If you have a dual-boot Windows/Linux system, you probably know this problem: you can access files from your Windows installation while you are in Linux, but not the other way round. This tutorial shows three ways how you can access your Linux partitions (with ext2 or ext3 filesystem) from within Windows: Explore2fs, DiskInternals Linux Reader, and the Ext2 Installable File System For Windows. While the first two provide read-only access, the Ext2 Installable File System For Windows can be used for read and write operations.

Tutorial quote: Instead of creating a new desktop setup every single time a new user comes along, it would be much easier to create some templates. If only there were an easy way to make and manage these templates.

Fortunately, we are not the first to ponder this issue. The creators of Sabayon decided to tackle the lack of a good desktop setting management tool. With Sabayon, they created an application that handles these problems and more.

Tutorial quote: If you dual boot with Windows and Linux, and have data spread across different partitions on Linux and Windows, you should be really in for some issues.

It happens sometimes you need to access your files on Linux partitions from Windows, and you realize it isn’t possible easily. Not really, with these tools in hand - it’s very easy for you to access files on your Linux partitions from Windows.
